Valve 12 includes valve body 20 and conduit 22, and valve body 20 includes outlet 18, and conduit 22 partly extends simultaneously in valve body 20
And including entrance 16.
Valve body 20 is for example made of two elements, the two elements are that housing lower half 20A and upper half-shell 20B (specifically exist
It is shown in Fig. 3).Housing lower half 20A and upper half-shell 20B respectively includes straight profiles, these half shells 20A, 20B pass through stacked
These straight profiles and be assembled to each other.The welding of " plane is to plane (flat on flat) " can make housing lower half 20A and
Upper half-shell 20B is fitted together in a traditional way.
In the described example, conduit 22 has circular cross section.However, alternatively, conduit 22 has ellipse
Cross section.Elliptical catheter allows to reduce the height of device 10.This elliptical catheter can along longitudinal direction be cut by assembling
Two semicanals cut are obtained or are obtained using hydraulic forming method from the conduit with circular cross-section.
Conduit 22 includes the distal end mouth edge 24 being arranged in valve body 20.The mouth edge 24 be located at conduit 22 in valve
The end of the part extended in body 20.
Mouth edge 24 extends in the planes completely.For example, the plane is tilted relative to the longitudinal direction X that conduit 22 extends
The angle being advantageously incorporated between 60 ° and 90 °.
Valve 12, which further includes, can surround pivot links 28 in the closed position of channel 19 (as shown in Figure 1) and releasing position (such as
Shown in Fig. 2) between the door 26 that moves.Pivot links 28 are supported by the support component being attached.
As shown in figure 3, half joint portion of two alignment of the pivot links 28 for example by being arranged on the both sides of conduit 22
28A, 28B are formed, and pivot links 28 have the axis R across conduit 22.This be arranged such that of pivot links 28 can reduce
The height of valve body 20.
Each free valve bodies 20 of half joint portion 28A, 28B support, and are more specifically supported by housing lower half 20A.
Advantageously, pivot links 28 are deviated relative to end edge 24 slightly towards entrance 16, so as to make door 26 relative to axis
Line R is deviated.
Therefore, for identical open angle, opening when pivot links 28 deviate between door 26 and mouth edge 24
Than be arranged in mouth edge 24 in pivot links plane in the case of bigger.In addition, it is arranged in mouth side with pivot links
Door in the plane of edge 24 is compared, and the pulsation for supporting 26 pairs of exhausts of door of this offset pivot connecting rod 28 is less sensitive.
Door 26 has flat contact surfaces 30, for straight with the mouth edge 24 of conduit 22 when door 26 is in the closed position
Contact." being in direct contact " means that door is directly shelved in the case where the mouth edge 24 is without additional intermediary element
In mouth edge 24.
The conventionally used operating lever actuating for being fixed to this 26 of door 26, the operating lever pass through conventional actuation device ---
Such as wax (wax) actuation device or electric actuation device --- it is mobile.
It should be noted that when device includes wax actuation device, the angle between the plane of mouth edge 24 and longitudinal direction X
Preferably substantially equal to 60 °, and when device includes electric actuation device, between the plane of mouth edge 24 and longitudinal direction X
Angle be preferably substantially equal to 90 °.
90 ° of angle is also advantageous, because not needing to pay special attention to the angle position of conduit 22 during the assembling of device 10
It puts.
Door 26 allows the surface bearing on the periphery of conduit 22 above the whole surface formed by mouth edge 24, this
Make it possible to ensure that the geometry of supporting surface.In fact, the geometry of supporting surface during welding assembly to by drawing
The deformation risen only has very slight susceptibility or completely insensitive.Advantageously, conduit 22 has the thickness for being substantially equal to 2mm
Degree, to have big supporting surface.
Door 26 includes the planar structure element 31 supported by pivot links 28.As previously mentioned, pivot links 28 are relative to this
Planar structure element 31 deviates.In other words, axis R is not passed through the planar structure element 31.
Advantageously, door 26 includes impact-absorbing element 32, such as metal ribs 32, for 24 phase of mouth edge with conduit 22
Contact.Therefore, in this case, 32 supporting plane contact surface 30 of impact-absorbing element.This metal ribs 32 pass through spot welding
It is assembled into structural detail 31.
Impact-absorbing element 32 is intended to limit when the arrival closed position of door 26 due between door 26 and mouth edge 24
Hit the noise generated.Impact-absorbing element 32 --- particularly when the impact-absorbing element 32 is made of metal ribs --- can
To be the minor leakage source between conduit 22 and valve body 20, but this leakage is very limited and can be neglected.It is this to let out
The leakage leaked particularly than being observed in the device of the prior art is much smaller.
Advantageously, door 26 further includes standpipe 34, which is supported by structural detail 31, opposite with contact surface 30.It should
Standpipe 34 makes it possible to increase the quality of door 26, and therefore reduces the specific frequency of door 26, then reduces by 26 pairs of exhaust arteries and veins of door
Dynamic susceptibility, and therefore reduce the vibration of door 26.
Heat exchanger 14 includes being in the exchanger entrance 36 being connected with valve 12 of 26 upstream of door and under door 26
The exchanger outlet 38 being connected with valve 12 of trip.Therefore, exchanger entrance 36 is connected with conduit 22, and exchanger outlet
38 are connected with valve body 20.
Advantageously, the standpipe 34 of door 26 is configured to close exchanger outlet 38 when door 26 is in releasing position.
For example, standpipe 34 has the shape being totally bent protruded from structural detail 31.Therefore, when reaching closing for door 26
During centre position between closed position and releasing position, standpipe 34 closes exchanger outlet 38.Therefore, in this case, i.e.,
Make when the stroke of door 26 does not complete, such as when device includes wax actuation device, exchanger outlet 38 is also turned off.
The open angle that standpipe 34 is for example configured to once reach 28 ° of door begins to close exchanger outlet 38.It is practical
On, the aging of wax actuation device depends on the number of actuating so that although when wax actuation device is new, open angle is
38 °, but the open angle is in the end-of-life of wax actuation device only 28 °.
Therefore, when reaching transition temperature in coolant circuit, the arch standpipe 34 of door 26 is inserted into exchanger outlet
In opening 38.Advantageously, which is provided with regulation ring, and when door 26 is opened, which is reduced in exchanger
Export the space that can be used for gas at 38.Therefore, exchanger outlet 38 is almost closed, and gas necessarily passes through conduit 22 and valve
Body 20 avoids exchanger 14 simultaneously.
In the example, retracting device 10 is included in the intermediate conduit extended between conduit 22 and exchanger entrance 36
40.The intermediate conduit 40 is laterally extended relative to longitudinal direction X.
Advantageously, what retracting device 10 was included in the inlet of intermediate conduit 40 can be by the gas from gas access 16
The upstream deflector 42 guided towards channel 19.The upstream deflector 42 made it possible to ensure that when door 26 is in releasing position,
Gas from gas access 16 passes through channel 19.
For example, upstream deflector 42 passes through the intermediate conduit 40 by the part extended in conduit 22 of intermediate conduit 40
The deformation of additional length is formed.
Advantageously, upstream deflector 42 extends to the height in the range of 2mm to 10mm in conduit 22.
According to alternative solution shown in Fig. 4, retracting device 10 includes downstream deflector 44, and the downstream deflector 44 is in centre
The entrance arranged downstream of pipeline 40 is arranged in the downstream of upstream deflector 42 in conduit 22.The downstream deflector 44 into
One step reduces the gas stream that exchanger 14 is flowed through when door 26 is in releasing position, so as to limit towards intermediate conduit 40
The section of opening.The vortex that the downstream deflector 44 also limits the downstream in upstream deflector 42 is formed, therefore reduces gas
Towards the flow velocity of exchanger 14.
Advantageously, upstream deflector 42 advances in conduit 22 in the height than the height bigger of downstream deflector 44.
In other words, upstream deflector 42 than downstream deflector 44 closer to the center of conduit 22.Therefore, it is deflected by upstream deflector 42
Gas do not deflected by downstream deflector 44 towards intermediate conduit 40.
For example, downstream deflector 44 extends to the height in the range of 2mm to 5mm in conduit 22.
According to an alternative solution, upstream deflector 42 and/or downstream deflector 44 and conduit 22 integrally, and pass through
The deformation of the conduit 22 obtains.
According to another alternative solution, upstream deflector 42 and/or downstream deflector 44 are by being attached at conduit 22 and intermediate tube
Part between road 40 is formed.
The operation of heat reclamation device 10 according to the present invention will be described now.
Retracting device 10 is worked using two kinds of operation modes, that is, energy recuperation mode and short-circuit mode.
When the temperature of cooling agent is less than the activation threshold of actuation device, retracting device 10 is in energy recuperation mode.Door
26 is in the closed position therewith, is supported in the mouth edge 24 of conduit 22.Therefore door 26 is closed in the end of conduit 22
The channel of exhaust.It exhaust from gas access 16 and then first passes through intermediate conduit 40 and orients, subsequently into exchanger 14
In gas access 36.Exhaust then passes through valve body 20, flows to gas vent 18 across exchanger 14.
When cooling agent reaches the transition temperature of actuation device, retracting device 10 is in short-circuit mode.Actuation device is therewith
Pivot links 28 are rotated, and therefore rotate door 26.The exhaust for reaching gas access 16 flows to valve body across put-through channel 19
20, and pass through the release opening between door 26 and edge 24.
Then, the standpipe 34 of door 26 closes exchanger outlet 38.
As previously mentioned, upstream deflector 42 can be by making air-flow limit exchanger 14 towards the lower part deflection of conduit 22
In a part of gas pass through.Therefore, gas naturally tends to follow conduit 22.In addition, the quilt substantially of exchanger outlet 38
It closes, is actually blocked by the gas passage of exchanger 14.
More specifically, when exchanger outlet 38 is essentially off, it is less than by the gas flow rate of exchanger through conduit 22
Gas flow rate 1%.
For example, the channel cross-section of exhaust is 60mm2, compared with the flow velocity 416kg/h by conduit 22, pass through exchanger
Flow velocity is only 2.4kg/h at 800 DEG C.It should be noted that in the case where deflector 42 and 44 is without regulation ring, which will be
9.7kg/h。
The method for being used to manufacture retracting device 10 will be described now.
This method must assure that door 26 when in the closed position with plane/plane contact of mouth edge 24.
Therefore, the step of this method is included for providing conduit 22, the mouth edge 24 of the conduit 22 for example passes through
It cuts, particularly is cut by laser conduit 22 and is pre-formed.Therefore, mouth edge 24 is limited to longitudinal direction X-shaped into predetermined
In the plane of angle --- such as 60 ° or 90 ° ---.
Next this method is included in the step of installation door support element on pipe 22.In the example, door support element passes through
The supporting member on valve body 20 is attached and is welded on to be formed.
Next this method includes door 26 being assembled on valve support element (valve body 20), pivot is installed in a manner of with clearance
Turn connecting rod 28.This clearance allows the flexibility of the positioning of door 26, most preferably to position the door 26.
Next this method includes door 26 being located in the closed position being in direct contact with mouth edge 24.Thus it positions
Door 26 permit a determination that the final positions of pivot links 28.
This method finally includes setting pivot links 28 relative to door branch according to the positioning of door 26 in a closed position
The position of support member (valve body 20).The position of pivot links 28 set in this way makes it possible to ensure that door 26 in the closed position will
Plane/plane contact is in mouth edge 24.
Next, the rest part of device 10 is assembled around conduit 22 and valve body 20.
It should be noted that since valve body 20 and intermediate conduit 40 are mounted on conduit 22, conduit 22 has in apparatus 10
There is structural support function.
It should be noted that the present invention is not limited to previously described embodiment, and various other replacement sides can be taken
Case.
Particularly, the overall shape of device 10 can be different from the shape shown in figure.
